First report of leaf blight of Turkish oregano (Origanum onites) caused by Neoscytalidium dimidiatum in Turkey
(SpringerLink, 2021) Alkan, Mehtap; Özer, Göksel; Koşar, İslim; Güney, İnci Güler; Derviş, Sibel
In July 2020, a leaf blight disease with intense defoliation on Turkish oregano (Origanum onites L.) plants was observed in a pilot experiment feld in Akçakale and a commercial feld in Haliliye with an incidence of 5.4 and 11.7%, respectively, in Şanlıurfa province. After a surface-sterilization for 1 min with 1% NaOCl, isolations from symptomatic tissues of six afected plants for each feld consistently yielded a fungus with the same colony morphology on potato dextrose agar. Cultures were powdery with a thick aerial mycelium, initially white that changed from olive green to black within 10 days.
First report of Macrophomina phaseolina causing charcoal rot on lemon balm (Melissa officinalis) in Turkey
(SpringerLink, 2022) Koşar, İslim; Güney, İnci Güler; Üner, Senem Ece; Özer, Göksel; Derviş, Sibel
Lemon balm (Melissa ofcinalis L.) is native to the Eastern Mediterranean region and Western Asia and is a well-known medicinal plant of Lamiaceae due to its valuable aqueous and alcoholic extracts (De Sousa et al. 2004). In the summer of 2021, wilting and root rot were observed on about 20% of two-year-old M. ofcinalis cv. Melis plants in a feld of Koruklu village, Akçatepe district of Şanlıurfa, Turkey.
First report of Neoscytalidium dimidiatum causing blight of Melissa officinalis in Turkey
(SpringerLink, 2021) Özer, Göksel; Günen, Tacettin Utku; Koşar, İslim; Güney, İnci Güler; Derviş, Sibel
In July 2020, a blight disease on lemon balm plants was observed with an incidence of up to 10% in three fields in Sanliurfa province, Turkey. The causal agent was identified as Neoscytalidium dimidiatum based on macro- and micro-morphological features of the colonies and sequencing of the translation elongation factor 1-alpha gene and the internal transcribed spacer region of rDNA. Re-isolation of N. dimidiatum from lemon balm plants showing blight symptoms was successfully established. To our knowledge, this is the first report of N. dimidiatum causing blight on lemon balm in Turkey and worldwide.
First report of Neoscytalidium dimidiatum causing foliar and stem blight of lavender in Turkey
(SpringerLink, 2021) Güney, İnci Güler; Özer, Göksel; Turan, İrem; Koşar, İslim; Derviş, Sibel
Lavender (Lavandula angustifolia Mill.) is a valuable medicinal and aromatic plant in Turkey, with a cultivated area of 2,218 hectares in 2020 (TURKSTAT 2021). In June 2020, wilting, extensive stem and leaf blight or necrosis were observed in two-year-old lavender plants cultivated in the experimental felds of the GAP Agricultural Research Institute, Şanlıurfa, Turkey.
